To all whom it may concern.-

Be it known that we, IVARREN M. BRINKER- HOFF, ABRAM W. SrEvENs, and LESTER D. SWAR'I, citizens of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Seeders and Rakes and we do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our present invention is an improvement in the class of seeders, and contemplates, among other things, the combination, with broadcast seeding devices, of mechanism for covering the seed, the said covering mechanism being of suchimproved character that it may be advantageously used for other pur- 2c poses. I

' In the accompanying drawings we have illustrated the best method in which we have contemplated embodying our invention, and our said invention is fully disclosed in the following specification and claims.

Figure l is a partial section vertical through the spring-tooth shaft, showing the manner of attaching the seed-box. Fig. 2 is a partial rear view showing the adjacent ends of the 0 divided seed-box. Fig. 3 is a vertical section through the spring-tooth shaft with seed-box removed to render the delineation of the parts more clear. Fig. a is apartial section of the spring-tooth shaft, showing the means for operating the cleaner-bars. Fig. 5 is a partial plan view, and Figs. 6 and? are enlarged side and plan views, of the tripping devices for the spring-tooth shaft.

In the drawings, Ais the shaft, to which are 40 attached the spring covering teeth of the seeder.

B is the draft-frame, composed of the shafts B B and cross-bar. This frame is provided with a seat for the operator, as usual in this class of machines. The shaft Ain this case forms the axle upon which are mounted the supporting-wheels, one of which is shown at D. The machine may, however, be constructed with an axle other than the shaft A, if preferred.

The shaft A is preferably of metal and formed from a pipe or tubing, as shown in the drawings. The springteeth a a are secured to the axleby two-part clips I) b,which are secured to the axle bya single bolt o The part b of the 5 5 clip is provided with asocket to receive a portion of the tooth,whichis turned at rightangles to the main body of the tooth in a well-known manner. The part b of the clip is provided with a spring-socket b the lower end of which is slotted, and the tooth passes through the slot, the walls of which serve as a guide to prevent lateral movements of the tooth, limiting this portion of the tooth to movements in a vertical direction only. In order to enable the. shaft A to be partially rotated to raise the teeth from the ground to move from place to place and for other purposes depending upon the use to which the machine is applied, as hereinafter explained, the shaft is provided with an arm A, rigidly secured thereto. To the outer end of this arm is pivoted a link 0, whichis in turn pivoted to a hand-lever C, pivoted to the draft-frame of the machine.

I The machine is adapted to be used as a rake, and in order to perform its work when so employed in the best manner is provided with the usual cleaner-bars c 6. These cleanerbars project from a cleaner-bar shaft E, which is mounted in brackets secured to the springtooth shaft A. The shaft E is formed from a metallic pipe. It is in this instance shown as divided, and each part is provided with an arm 6 6, formed by bending a portion of the pipe at right angles and then flattening the same. The outer ends of these arms are provided with apertures for the reception of a bolt 6 which forms a pivot for a link a which is at its opposite end pivotally secured to the seat-support, as shown, or to some part of the 0 draft-frame. The rear end of the link is provided with a slot 0', which permits the cleaner-bars to rise in case of the materials gathered by the teeth rising against them. It will be seen that in case the shaft A is rotated and the teeth a a raised the link 6 will serve to partially rotate the cleaner-bar shaft in a reverse direction, which will move the rear ends of the cleaner-bars downward to assist in freeing the teeth from gathered materials. I00

The lowest position reached by the cleanerbars is shown in dotted lines, Fig. 3.

The seed-box F is divided into two parts, as shown in Fig. 2, to permit the free action of the arms 6 of the cleaner-bar shaft. It is secured in the position shown by straps or clips f, engaging the spring-sockets of the shaft A, and is provided with a series of sliding valves f for discharging the seed, corresponding in number to the spring-teeth of the shaft A. Each of these valves is provided on its forward side with a groove or recess f (shown in dotted lines in Fig. 2,) which is normally below the bottom of the seed-box. In Fig. 1 these valves are shown as sliding within the box and in Fig. 2 as sliding within guides f on the outside of the box. In the latter case the box is provided with an opening corresponding in dimensions with the recess in the valve, and is so placed that a slight upward movement of the valve causes the two to register, when the the recess of the valve will be filled with seed, and a slight downward movement of the slide will cause it to discharge the seed held in the recess. As the teeth are in constant motion when engaging the ground, a simple and effective discharge of the seed is thus secured, and the seed when discharged falls just in front of the ends of the spring-teeth, whereby it is most efficien tly covered by the same.

The machine is, as heretofore stated, adapted to be used as a rake when desired, and we provide a trip of peculiar construction by which the shaft A is rotated to raise the teeth by causing it to be momentarily engaged with the wheels. This construction is best shown in Figs. 5, 6, and 7. In Fig. 5 the details at one side of the machine are shown; but as these features are not new the corresponding parts at the opposite side are omitted. The wheels D are provided on their inner sides around their hubs with a notched disk (Z. On the axle or shaft A is pivoted a dog d, adapted to engage the notches of this disk. Rods d connect these dogs with parts located centrally of the shaft and within easy reach of the operator for effecting the movement of the dogs when desired. The disks, dogs, and connecting-rods are all old and well known in the art. To effect the movement of the dogs through the rods, we employ a quadrant G, which is pivoted at g to the shaft A. The rods (Z pass through the quadrant on opposite sides of its pivot and are provided at their ends with nuts. On the opposite side of the quadrant each rod is provided with a spring g, engaging the side of the quadrant and held to this engagement by a pin or other means secured upon or in said rod. These springs hold the nuts against the opposite sides of the quadrant and receive the force applied to the quadrant when turned on its pivot to force the (logs into engagement with the notches of the disks. The portion of the quadrant G extending forward of its pivotis slotted, as shown, and is moved to effect the engagement of the dogs (7. with the disk (l by a crank-pin h on rock-shaft H, mounted in suitable bearings on the draft-frame. This rock-shaft is provided with a hand-lever or treadle by which it may be operated. In the drawings it is shown as provided with the treadle I. The rock-shaft H is provided with a spring h, which tends to maintain the shaft and quadrantin such position that the dogs cl are held out of engagement with the notched disks. This spring also serves to return these parts to this position when pressure on the treadleis removed by the operator. In order, however, to automatically effect the releasing of the dogs and to prevent the operator through inadvertence from carrying the movement of the shaft A beyond the proper point to discharge the teeth, the quadrant is provided 011 one side with the lugs 9 and the draft-frame is provided with a trip 71,2 in the path of the projection g of the quadrant. When the shaftA has been turned such distance as to raise the teeth to their highest position, the lug 9 comes in contact with the trip Wand the further rotation of the shaft A turns the quadrant in the proper direction to free the dogs from the disks,when the teeth will descend to the ground by their own weightand all accident to the dumping or discharge devices is avoided.

In case the dogs (1' should be forced against the projections between the notches on the disks, the springs g will yield; but the full force of the springs will be exerted against the dogs and force them into engagement with the succeeding notch, thus avoiding jar and insuring the action of the discharging devices.

hen the machine is used as a rake,if preferred, the seed-box may be removed.

What we claim, and desire to secure by Letters Patent, is-

1. In a seeder, the combination, with the seed-box and delivery-valves, of spring covering-teeth connected with said valves, substantially as described.

2. In a seeder, the combination, with the seed-box having independently-operated delivery-valves, of spring covering-teeth, each valve being connected with a single coveringtooth, substantially as described.

8.
